This invention relates to improvements in the art of waving human hairand has-particular reference to holding devices for a wound strand ofhair.

Holding devices including clamps and curler rods have been heretoforedevised wherein the clam is utilized to grip a strand of hair close to te seal and to receive the curler rod upon which t 1e strand is wound.The clamp usually consists of a pair of pivotally connected bars adaptedto be brought together to securely hold the hair strand therebetween,and is provided with means cooperating with the curler rod to tightlywind said strand thereon and maintain the latter under tension. Thecooperating means customarily emplo ed consists of a ratchet formed onone en of the curler rod and a pawl carried by the clamp which isengageable with the ratchet so as to prevent rotation of the rod in adirection which would relieve the tension on the hairstrand and allow itto become loosened on said rod. With the strand of hair thus heldbetween the bars of the clamp and wound on the rod, the lat ter is heldagainst the clamp at least partly by the tension under which the strandhas been-placed, and cannot conveniently be re moved until said tensionis relieved. In the types of appliances heretofore used, the release oftension after treatment of the hair strand is accomplished by firstseparating the bars of the clamp after which the curler rod and hairstrand may be shifted slightly in a longitudinal direction relative tothe clamp in order to disengage the ratchet of the rod from the pawl ofthe clamp, whereupon the rod may be rotated to unwind the strandtherefrom.

It has been found in practice that the separation of the bars of theclamp, preparatory to unwinding the hair strand after treatment,

' requires some skill in the proper handling ments of the pawl of theappliances as it entails the necessity of the operator holding both theclamp and the curler rod in order to accomplish the shifting of thelatter to disengage the eleand ratchet mechanism.

In accordance withthe present invention it is :proposed to simplify theoperation of releasing the hair strand from the curler rod by a suitablemeans the use of which will 7 avoid the necessity of the operator firstseparating the bars of the clamp and holding the same while shifting therod and strand 1982.

relative to said clamp in order to disengage the parts of said pawl andratchet mechanism one from the other.

In accomplishing this simplification it has been found satisfactory toprovide the pawl with a finger-piece by which it may be released fromthe ratchet mechanism, and in one preferred form of the presentinvention such pawl is provided with an abutment which may be desirablylocated to serve as a finger abutment so as to-limit the movement of thepawl in releasing the ratchet.

he inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which, for purposes of illustration, isshown in the accompanying drawing wherein Figure 1 is a rspective viewof the clamp and curler ro illustrating a hair strand in the act ofbeing wound upon the rod while held by the clamp.v

he apparatus shown inthe accompanying drawing consists generally ofthree elements, namely a clamp 10, curler rod 11 and an electric heater12. In use, the clamp is first employed to gri a strand of hair 13adjacent the scalp, a ter which said strand is wound u on the rod 11, inthe manner illustrated in igure 1. When the strand is completely woundupon the rod, the latter is unengaged with the clamp in a manner to bepresently described in detail, and the strand is then wrapped in a pador sachet (not shown) which is moistened with a hair treating solu-'tion. The heater 12 is then placed about the strand and heat applied fortreatment of the strand in the customary manner.

The fresent clamp is shown, in its preferred orm, as comprisin the twocooperating clamping bars 14 am? 15, the former of ENT OFFICEJ which ismade of a suitable insulating ma- I terial while the bar 15 consists ofa metallic rod 16 covered by a sleeve 17 of rubber or other suitableinsulation. The inner edge of gitudinally with supporting the rod on tthe bar 14 adjacent the bar 15 is concaved as indicated at 18 (Figure 5)so as to receive a portion of the sleeve 16 to thereb provide maximumgrip in surfaces for t e clamping bars which 01 the hair strandtherebetween.

At the ends of the bar 14 the same has suit-- abl secured thereto thebearing members 19 an 20, the former of which is provided adjacent itsbase with a lug 21 to which is pivoted the ad'acent end of the bar 15.The other end 0 said bar carries a latching device consisting of a link22 pivoted atone end to said bar and, in turn, having pivoted to itsother end a cam lever 23. When the clamping bars have been brought intocooperative relation with the strand 13 therebetween the link 22 isswung to a position arallel with and against the adjacent end 0 the bar14 and the lever 23 is then extended lonthe outer edge of said bar, asshown in Fi ure 1, to lock the clamping bars together. i Vith the clampin its 0 erative position, be wound upon the curler rod 11.

The body of the rod is tapered inwardly from both ends as is customarywith rods of this ty e and adjacent one end thereof has pivote thereto aretaining arm 24 which extends longitudinally of the rod and is adaptedto have the free end of the strand interosed-between the same and saidred at the Beginning of the winding operation. The strand is now woundupon the rod in the manner shown in Figure 1 and as the windingoperation progresses clamp and finally contacts the same with the endportion 25 of the rod engaged in the recess 26 of the bearing 19 and thetrunnion 27 at the opposite end of the rod engaged in the recess 28 inthe bearin member 20, thereby efclamp. At the outer end of the portion25 of the rod there is formed a ratchet 29 which is disposed exteriorlyof the bearing member 19 when the rod is in osition and which is adaptedto be enage by a pawl E the numeral 30 and carried by the bar 14.

his pawl and ratchet mechanism is designed to prevent rotation of thecurler rod in one direction and at the same time permits of a turning ofthe rod in the opposite direction, by the application of a key to thesquared end 31 of said rod, to tightly wind the strand 13 on the rod andthereby place said strand under the desired tension for the wavingprocess.

The pawl member 30 ecifically comprises a base portion 32 secure in theadjacent end of the bar 14 and having extending upwardly from one endthereof the curved spring arm .33 which is of sufiicient length andresiliency to normally maintain the pawlor tooth 34 thereof in enagement with the teeth of the ratchet 29 an at the same time permit ofthe under which the latter the strand 13 is now rea y to the rodapproaches the member generally indicated withdrawal of said pawl fromthe ratchet without undue pressure having to be exerted upon said arm.The latter is extend be end the pawl 34 to rovide a-fingerpiece 35 aiiording a means w ereby the operator may easily press the arm in adirection away from the ratchet 29 and thus disengage the pawl 34 fromthe teeth of said ratchet- To facilitate this releasing action thebearing member 19 is provided with a second fingerpi'ece 36 disposed injuxtaposition to the piece 35, and being stationary, said piece 36provides a grip by means of which the movable fingerpiece can be morereadily pressed in a direction away from the ratchet 29.

In the types-of clamps and curler rods usually employcd,when it becomesnecessary to unwind the strand of hair from the curler rod aftertreatment of said strand, the tension has been placed by the operationcauses such an interenga ement of the clamp and curler rod that in or erto conveniently release the latter from said clamp, the clamping barsmust be first separated to relieve said tension. When this has beendone, the curler rod with the strand wound thereon is free to be shiftedslightly in a longitudinal direction relative to the clamp so as todisengage the ratchet on the rod from the pawl ofthe clamp, whereuponthe unwinding of the strand from the rod by rotation of the latter maybe accomplished. While performing this operation, the operator must holdthe clamp while the rod is being shifted. In contradistinction, thepresent device provides a more simple and efiicient manner 0 releasingthe curler rod for the purpose of unwindin the strand therefrom,inasmuch as it is only necessary for the operator to press upon thespring arm 30 to disengage the pawl and ratchet whereupon the strand maybe unwound from the rod by a direct movement of the latter away from theclamp.

It will be noted in the construction shown it will not be possible forthe operator to bend the pawl finger-piece 35 so as to unduly strain it,since when the pawl finger-piece 35 is moved sufficiently to release thepawl 34 from the .ratchet 29, such pawl finger-piece 35 will abutagainst the finger-piece 36. This feature is particularly importantinasmuch as the resilient element is relatively delicate and ma beeasily injured by excessive strain. It has en found that the squeezingmovement necessar to release the pawl 34 by moving the pawl nger-piece35 against the abutment 36 is most satisfactory, and is more susceptibleto ready actuation by the operator.

When the finger-piece 35 is moved into contact with the abutment 36which limits its movement, the pawl will be lifted out of the ratchet 29which will then be free. It is to be understood, however, that thepresent invention also includes other relationships between the pawlfinger-piece 35 and the abutwinding plates ment fingeroperator to p aceher thumb against one fin er- )iece and the index finger against theother an readily release the combination, as p viously described. It isalso generally desirable to have both the abutment fin er-piece and the)awl finger-piece located ad acent to one of the bearing elements ormembers 19 attached to the end of the bearing 14 of the clampin member.The e ectric heater 12 is shown as comprising a pair of elongatedheating elements 37 which are curved transversely and adapted to engageon opposite sides of the wound strand of hair on the curler red, as bestshown in Figure 3. These heating elements are supported by upwardlyconverging 38 and to the intermediate portion of each plate is secured ahandle 39 made of suitable insulation material and throu h whichelectrical conductors 40 extend or conveying current to resistance coilsdisposed within each of the heating elements 37 n opposite sides of eachhandle the associated supporting plate 38 is provided with theextensions 41 which diver e outwardly relative to the extensions on 51copposed plate. Each pair of the opposed extensions of the respective 42to receive a spherical member 43. These members on opposite sides of thehandles 39 constitute bearings about which the handles have a pivotalmovement so that the heating Elements 37 may be adjusted toward and awayfrom each other.

To assemble the opposed heatin elements, their supporting plates andhand es into an operative unit and provide means for forcing theheatingelementstoward each other so that they will securely gripopposite sides of the hair strand, a contractile sleeve-like spring 44is associated with each pair of extensions 41. .Each spring is splitlongitudinally so as to receive said extensions therebetween and thusexert a ressure upon the outer surfaces thereof wluch will normallyforce the heating elements toward each other. In order to preventaccidental displacement of the spring members alon one of itslongitudinal edges, as indicated at 45, to provide at the ends of thesleeve a pair of lugs 46. The length of the cut out portion 45 issubstantially equal to the width of the adjacent extension 41 so thatthe latter will engage in said out out with the lugs 46 overlapping theedges of the extension and thus preventing a lateral shifting of thespring member relative to the adjacent handles 39.

From the foregoing, that by compressing the free ends of the handles 39the heating elements 37 may be spread apart against the action of thesprings 44, preparatory to mounting the heater in operative relation toa hair strand, and that upon it will be apparent iece 36 which willenable the plates is provided with openings.

44, each of them is cut away I 4 ment of the release of said handlessaid spring members will be efi'ective to clamp the heating elementsagainst the strand and thus maintain the eater in position forapplication of heat to the hair belng waved.
